' 6 Claims. (01. 251-419) My invention relates to a control valve for water bells. It has to do, more particularly, with a control valve adapted to be associated with a water supply bell of the type disposed in the drum of a concrete mixer, such as a truck mixer. It is applicable to the water bells disclosed in Figures 1 to 3 of the copending application of Gebhard Jaeger, Serial No. 201,250,;filed April 11, 1938.; However, it may be employed with other types of water bells. I

One of the objects of my invention is to provide a control valve for water bells of thetype indicated which is of such a nature that it will permit efficient discharge of the water into the f loaded mixing drum without danger of the material in the drum entering the bell or rendering the valve inoperative.

Another object of my invention is to provide a valve of the type indicated which is of' such a nature that it will open readily and efliciently when water is supplied to the water bell'and will close and seal itself when the flow of water thereto is interrupted.

Anotherobject of my invention is to provide a valve of the type indicated'which is of such a" nature that the parts thereof will not beworn readily by the concrete in the drum so that the valve will leak after being used for a short period.

Another object of my invention is to provide a 1 valve of the type indicated in the preceding paragraph which is of such a nature that if any part does wear to an undesirable extent after long usage, it may be removed readily and replaced.

The preferred embodiment of my invention is illustrated in the accompanying drawing wherein similar characters of reference designate corresponding parts and wherein:

Figure 1 is a side elevation, partly'broken away, illustrating a truck mixer with water bells disposed therein to which my control valve may be applied.

Figure 2'is a sectional view taken throughthe casting which form the water bells and showing my valve applied to eachof the bells.

I Figure 3 is a-view looking into one of the bells,

of my control valve in spaced relationship.

With reference to the drawing, in Figure 1 I have shown a truck mixer embodying a rotatable mixing drum l. Within the mixing drum a water V pipe. 2 is am'ally disposed and carries a casting 3- which has water bells 4 and 5 formed thereon as described in the copending application S. N. 201,250. 'My control valve is adapted to be applied to each of the water bells 4 and 5. However, it is'to be understood that it may be applied to various other types of water bells. According to the present invention each of the water bells is provided with a frusto-conical or bell shaped portion 6 at its outer end. At the inner end of portion 6 a supporting spider 1 is formed integral with the bell casting. This spider 7 has a hub portion 8 having a threaded opening formed therein. i

The valve itself is formed by an inner disk 9 of steel which is of concave form. This disk has a chamfered edge In which will contact with the inner surface of the portion Ii. The steel disk 9 has secured to its outer surface a gum rubber disk H which will also be of concave form and will lie in contact with the steel disk throughout its area. This rubber disk is also provided with a chamfered edge "which contacts the inner surface of portion'fi and produces a seal at this point. The disks 9 and I l are secured together by a plurality of rivets I3 disposed around the center thereof and closely adjacent to same. These two disks are provided with aligning openings H which are disposed at circumferentially spaced points and which are spaced a substantial distance from the peripheral edges of the disks. The disks 9 and l l are secured together as a unit by 'the rivets 13. To prevent the rivets from pulling through the rubber disk I l a small metal disk I5 is provided which bears against the outer surface of rubber disk ll adjacent the center thereof. A second gum rubber disk I 6 is provided which is adapted to bear against the outer surface of the rubber disk II. This disk is flat before being mounted in the valve. It is held in position by means of a small metal disk or a washer I! which bears against the center portion only thereof. The washer I1 is held in position by a bolt l8 which passes through aligning centrally disposed. openings formed in members IT, IS, II and 9 and which is threaded into the hub 8' of the supporting spider 1. Thus all of these members will be tightly clamped together. A lock Washer I9 is provided for normally preventing loosening of the bolt. The disk I6 is of such diameter that its peripheral edge will not contact with the innersurface of portion 6 of the bell. Although the disk is fiat before being positioned in the bell, it will assume the curvature of the disk 1 I when it is mounted in the bell and will seat on the disk ll substantially throughout its area. V

It will be apparent that this valve is normally closed. The disk It will normally be seated on the disk [I and will effectively seal the openings M. The edge I2 of the disk II will seat against the inner surface of the bell and will produce an effective seal at this point. The edge of the disk 9 will also seat against the inner surface of the bell and form a seal.

When water is supplied to the bell under pressure, it will pass out through the opening l4 forcing the rubber disk l6 outwardly and will be sprayed outwardly by the portion 6 of the bell, as indicated in Figure 4. The water will not pass around the edges of the disks 9 and H since seals are formed at these points. As soon as the water pressure is eliminated, the disk [6 will again seat on the disk II. This will prevent any concrete from entering the valve.

The pressure of the concrete on the disk l6 will merely enhance the sealing action. Furthermore, if any particles do work under the edges of the disk [6, the seal will not be affected because there is a rubber to rubber contact of the disks II and I8. Furthermore, because of this rubber to rubber contact there will be substantially no wear produced by any particles entering between these members. If it is desired to remove any parts, this may be readily done merely by removing the bolt l8.

With this combination an improved sealing of the water bell is obtained. The holes 14 are covered by the outer rubber disk l6 even though the edge of this outer rubber disk is worn or wrinkled. This combination, in effect, offers a double seal. First, the perimeter inside the bell is sealed by the combination rubber and metal disk 9 and l I, having the holes 14. Secondly, the outer rubber disk lfiseals the perimeter, and, even if there is failure at this point, it still further seals against the holes I4. Thus, even if the outer rubber disk becomes wrinkled badly or worn badly, or a stone catches under the edge thereof, the holes M are still sealed by this outer rubber disk.

It will be apparent from the above description that I have provided a valve for water bells having many advantages. The valves will open readily and efficiently when water is supplied to the bell and will close and seal itself when the flow of water thereto is interrupted. When closed there will be no danger of the concrete entering the bell or rendering the valve inoperative.

Various other advantages will be apparent from the preceding description, the drawing, and the following claims.
